As we can see, Swinford was spelt Swineford, in 1846.
Swinford is a market and post town, in the parish of Kilconduff, Barony of Gallen and County of Mayo, 140 miles N.W. of Dublin, 19 miles N.E. of Castlebar, 17 miles N. of Clare, and 15 miles S.S.E. of Ballina, seated on elevated ground and derives it's name from a fordable stream, which passes by the town, and near which was formerly held a considerable market for Swine. The place enjoys, at the present day, little importance from it's trading transactions and none from it's architectural embellishments. The principal business establishment is that of Mulligan and Co. drapers and merchants. The Court-house is a good and convenient building, lately erected therein general sessions are held in April and October, and petty sessions every Tuesday.
The Parish Church of Saint Mary is a small Gothic building, with a Tower, erected in 1810, and subsequently repaired by means of funds granted by the ecclesiastical commissioners. The living is a vicarage and includes the united parishes of Kilconduff, Meelick, and Kilbeagh. The Roman Catholic Chapel in appearance is unostentatious, but is a convenient structure. A school, lately established under the National Board of Education, for children of both sexes, and barracks for the constabulary and revenue police forces, are the only public establishments.
The Market is held on Tuesday for pigs, provisions, corn, etc.
Fairs are held on : February 1st, March 17th, May 20th, July 2nd, August 18th, Oct 29th and Dec 18th.
